4 open source boards using the ESP-01S
Real designs built with the ESP-01S, from public GitHub projects: a quick way to see how others power, decouple and connect it. Each board comes with its KiCad files, full parts list and a render — and you can simulate its firmware on HardLabs.

ESP-01S: common questions
Where can I find a ESP-01S reference design?
Each of the 4 boards on this page is a real design using the ESP-01S. Open one to see how it is wired up, with the full BOM, a render of the layout and links to its KiCad files.
Which microcontrollers do boards using the ESP-01S use?
Most are built on ESP8266 (3).
How big is a typical board using the ESP-01S?
The median is 74.8 × 63.9 mm, and 100% are two-layer designs.
What is the most popular open source board using the ESP-01S?
By GitHub stars, Doorbell sensor by thorio, with 28 stars.
Can I simulate one of these boards using the ESP-01S before building it?
Yes. HardLabs turns a board's netlist and BOM into a working simulation, so you can boot and test firmware against it with no hardware on your desk.
